When tli e generator is started. upand after its voltage has risen to a predetermined value the stren h ofmagnet coil 15 becomes suflicient to ralse the armature of switch '14 sothat the battery 6 is connected across the wires or conductors 12 and 13with the booster 17 in sefies therewith. The magnet coil16. is alsoconnected in series therewith at the 'same time, and the feedingconductors or wires 12 and 1-3. The work circuits 5 are fat the sametime connected across the conductors Band 26 and thus fed. from thegenerator 1 in parallel" with the batteries 6 and the extra voltagenecessary to cause the batteries to'be charged full load upon the workcircuit 5 the strength of field coil 21 is-such that thecounter-machine19 produces .a voltage exactly equal to but 0 po'site indirection to that applied to, the circuit 20 by the generator 1.Therefore, no current will flow. in the field coil 18 of the booster andthe booster Will generate no voltage and the battery will be allowed tofloat across the line. When the load on thework circuit 5 decreases aridelectromotive iorces in circuit 20 become unbalanced a; current is sentthroughthe fie'ld coil 18 of'the booster in a direction to cause thebooster to produce an electromotive'force in a directionto cause thebattery to'be charged, thus tending to maintain the load on each ofthetrain units constant. When the main generator is being shut down, 'ata certain point, the voltage of the batte'ries '6 will be greater thanthat of the generator and a reverse current will flow through the seriescoil 16 of the switch reversetcurrent in coils '16will oppose that ofcoils "15, thereby greatly decreasingthe attractive action of thesemagnet coils a lowside 0 the generator is entirely. disconnectedfrom'the batteries and Work circuits on the rious units.

It will further be apparent that-upon theshuttingdown of the generator the various.trainconductorsare renhave beendetermined the load on the main generator is maintained substantiallyconstant.
